Penerangan
Jalur keluli tahan karat 321 ialah sejenis keluli tahan karat austenit dengan kandungan karbon rendah dan rintangan kakisan yang baik kepada banyak persekitaran yang menghakis.321 menawarkan kebolehkimpalan yang sangat baik, kebolehmesinan yang baik dan sifat fabrikasi yang cemerlang.
Jalur keluli tahan karat 321 biasanya digunakan dalam industri kimia, industri pulpa dan kertas, industri kejuruteraan marin dan luar pesisir serta dalam industri makanan dan minuman.
Jalur keluli tahan karat 321 juga mempunyai tahap rintangan yang tinggi terhadap keretakan kakisan tekanan klorida dan pitting.Ia juga tahan kepada asid hidroklorik pada suhu tinggi sehingga 250°C (480°F).
ciri-ciri
Rintangan Kakisan yang Baik: Jalur keluli tahan karat 321 mempunyai rintangan kakisan yang lebih baik daripada 304 dan 316 jenis keluli tahan karat, yang menjadikannya sesuai untuk digunakan dalam persekitaran yang menghakis.
Kebolehkimpalan Cemerlang: Jalur keluli tahan karat 321 boleh dikimpal dengan semua kaedah termasuk kimpalan arka ( TIG / GTAW ), kimpalan rasuk elektron ( EBW / EFW ), kimpalan arka tenggelam ( SAW ) dan kimpalan sinar laser ( LBIW ).
Kekuatan Tinggi: Tahap kekuatan jalur keluli tahan karat 321 adalah sehingga 50% lebih tinggi daripada 304 jenis keluli tahan karat dan sehingga 80% lebih tinggi daripada 316 jenis keluli tahan karat kerana peningkatan kandungan karbon dan saiz butiran austenit.
